Manufacturing of HTS composite wire for a superconducting power transmission cable demonstration

American Superconductor Corporation, Pirelli Cable Corporation, and the Electric Power Research Institute are engaged in a program aimed at developing a commercially viable high temperature superconducting power transmission cable, The first phase of the program has been completed with the fabrication and testing of a 50 meter conductor for a power transmission cable, Over 12,000 meters of wire have been manufactured and thoroughly tested. In this paper, we will present and discuss data of the production wires used in the 50 meter conductor. In addition, we will discuss electrical and mechanical performance data used to qualify a high performance, high strength wire.
